This rifle is built on a forged A4 upper and lower receiver set, ensuring a solid foundation. The mid-length gas system is a smart choice for a 16-inch barrel in this caliber, reducing felt recoil and wear compared to a carbine-length system. The included 10-round magazine gets you to the range immediately. With an overall length around 35 inches and a weight just under 7.5 pounds unloaded, it balances well for offhand shooting or carrying in the field. The price point of $1242.07 positions it as a serious tool for a specific job.
Who This Rifle Is For
This is for the Missouri hunter who needs a straight-wall cartridge for deer season but wants the familiar ergonomics and modularity of an AR-15 platform. It’s also for the shooter who values a refined trigger and modern mounting solutions over a bare-bones build. When it comes to setting up a dedicated stand rifle or a reliable woods-walking companion within legal constraints, this RRA model is a focused answer. It works with standard AR-15 lowers chambered in 350 Legend, offering flexibility for future builds or parts compatibility.
Pros & Cons
Pros: The 350 Legend cartridge delivers significant energy with manageable recoil, making it effective for medium game. The M-Lok handguard is a major upgrade for mounting lights, slings, or grips without adding excessive weight. The two-stage trigger is a standout feature you’d typically pay extra for—it provides a tangible accuracy advantage. Here’s the thing—no gunsmithing is required to start using this capable system.
Cons: Ammunition cost and variety for 350 Legend isn’t on par with .223/5.56, so practice may be more expensive. The 10-round magazine capacity is standard for the hunting role but less than typical AR magazines. Some may prefer a longer handguard, but the 13″ length provides ample real estate while keeping the front end light and maneuverable.
Frequently Asked Questions
Q: Is the 350 Legend suitable for deer hunting in Missouri?
A: Absolutely. The 350 Legend was developed specifically to meet straight-wall cartridge requirements in states like Ohio, Iowa, and Michigan, and it is an excellent, legal choice for Missouri whitetail. It offers ballistics superior to many traditional pistol-caliber carbines used for the same purpose.
Q: Can I use standard .223/5.56 magazines with this rifle?
A: No. While the lower receiver is mil-spec compatible, the 350 Legend cartridge requires specific magazines due to its different case dimensions. The rifle includes a 10-round 350 Legend magazine, and others are available from brands like C-Products Defense.
Q: What optics are recommended for this setup?
A: For hunting, a low-power variable optic (LPVO) in the 1-6x or 1-8x range is ideal, allowing for quick close-range shots and precise aiming at distance. A quality red dot sight is also a great option for fast, intuitive shooting inside 100 yards. The flat-top upper receiver is ready for any standard Picatinny-mounted optic.
